Meshfree 3D Crack initiation, propagation, junction in non-linear materials: large strains, statics and dynamics without front enrichment A Lagrange multiplier method
Overview & Synopsis
We present in this paper a technique based on Lagrange multipliers to close the cracks along their fronts when analyzing three-dimensional fracture mechanics problems in statics and dynamics with the enriched element-free Galerkin (EFG) method. This Lagrange multiplier field avoids the use of near-tip enrichment, thereby only requiring discontinuous enrichment to account for the presence of the cracks. We show that the methodology performs quite well, even for very large strains and fragmentation.
